Serial No, 243,030. Patent No.-..1,708,615, datedApril 9, 1929. Divided and this application filed February 8,1929.Serial No. 338,469. a

This invention relates to a device for holding stripsheet metal, as forexample, when joining together the free ends of the strip as by welding.

This application is a division of our 00- pending application Serial 0.243,030, filed December 28, 1927, Patent No. 1,708,615, dated April 9,1929, which discloses a method of shaping sheet metal to produce aquarter window finish molding for an auto mobile body. I

It is the object of the invention to provide a device for holding stripsheet metal in various desired positions when performing a mechanicaloperation thereon such as welding the free ends ofa strip of sheet metalpreviously flanged and shaped to polygonal form with the free endstogether as described in our above mentioned co-pending application.

The invention will be more clearly understood from the followingdescription taken in conjunction with the accompanying drawing; inwhich,

Fig. 1 is a front elevational view of a device embodying the invention;

Fig. 2 is an end elevational view of the Fig. 3 is a sectional Viewtaken upon line 3-3 ofFig. 1, showing the frame in a horizontalposition.

Fig. 4 is a sectional view taken upon the line 44 of Fig. 1, showing theframe in vertical position.

Before explaining in detail the present invention, it is to beunderstood that the invention is not limited in its application to thedetails of construction and arrangement of parts illustrated in theaccompanying drawings, since the invention is capable of otherembodiments and of being practiced or carried out in various ways. Alsoit is to be understood that the phraseology of ter minology employedherein is for the purpose of description andnot of limitation, and it isnot intended'to limit the invention beyond the terms of the severalclaims hereto appended as considered in view of the prior art and therequirements thereof.

One embodiment of the invention is illustrated by the device shown inthe drawing which comprises a table (Figs. 1 to 4) having a plate 16secured to the top surface thereof in any suitable manner as by screws17. A 'framecomprising a T-shaped base 18 having a slot 14, is providedwith cylindrical projections 19 mounted in bearings 20. The bearings 20are secured to the table 15- by bolts 21 passing freely through openings22 in the table and extending beyond the lower surface of the table. Theextension of each of the bolts 21 is surrounded by a spring 23 extendingbetween a Washer 24 abutting the bottom surface of the table and awasher 25 held andsecured near the outer ends of the bolts, by'nuts 26.The T-shaped frame is provided with upright sides engaging the uprightmembers 28 and with the portions adjacent the free ends of the strip ofsheet metal engaging the T-. shaped frame member 18 directly above theslot 14. With the. frame in'a vertical posi-' tion the free ends of thebody of the strip of sheet metal are welded together and the frameisturned to bring the frame members 28 to a horizontal position. The freeends of one set of flanges are then welded together and the frame turnedto bring the members 28in a horizontal position on the opposite side ofthe. original vertical position andthe free ends of. the other set offlanges are welded together. The springs 23 "permit yield of thebearings 20 to provide clearance for the bottom of the T-shaped frame 18when being turned and yet hold the frame rigidly in the position towhich it has been turned.

What we claim is: In an apparatus for forming a flanged strip ofsheetmetal to polygonal shape, the combination of a support, a frameadapted to engage the sides of the polygon to hold the free ends of thestrip of metal together while being welded, said frame comprising amembers 28 secured to the frame adjacent
